Are there cultures in which the decimal separator

问题:

I must write a stringToNumber parsing function that can use custom strings for the following:

  • decimal separator (. for en-US => 3.1415)
  • thousands separator (, for en-US => 1,000,000)
  • positive sign (+ for en-US => +5)
  • negative sign (- for en-US => -5)

Can I assume that these are only one character (which would make the implementation easier) or are there any cultures in which any of these are longer?
